USA Market Mircobrewing

I'm traveling in the US right now, and it's amazing. In every small village, there is a micro-staffing bar. In the bar, only the beer is served at the front, which is brewed at the back. The mark is huge, and even the big beer companies (Budlight) have respect for this movement.Now back in Germany I miss such Mircobrewingbars, and ask me why this concept does not prevail here? What is your opinion?Or are there such bars and I can not find them?
